WATER-CLOSET.

SPECIFICATION formingpart of Letters Patent No. 270,113, dated January2, 1863.

Application filed October 5, 1881. (No model.)

ment. Fig. 2 represents an elevation, partly in section, of an ordinarywater-cock for a water-closet adapted for use'to subserve the IS purposeof my invention. Fig. 6 is a detail elevation of pan-operatingmechanism.

My invention has for its object to provide a water-closet which willabsolutely prevent the passage through itof sewer-gas and odorsgenerated by the fecal matter remaining in the trap, thereby obtaininga'.water-closet which is, as near as may be, perfectly inodorous.

My invention accordingly consists of a water-closet provided with arunning-water seal or a seal the water of which is constantly beingchanged or kept fresh. Said seal may be effected in various ways,depending upon the style of the water-closet used.

' In the accompanying drawings I have illus- 0 trated a number ofdifferent kinds of watercloset bowls provided with means for effecting arunning-water seal therefor, and which I shall now proceed to describe.

In Fig. l the bowl A is represented as be- I ing devoid of a pan, havingin lieu thereof a cap, B, which enters a groove, 0., in the upper edgeof said bowl. From said groove depends a conduit, 11, to the end ofwhich is secured the water-cock O. 0 represents the inlet-ori- 0 ficethereof, and c the outlet,-t0 which is connected theflushing-pipe E. Thevalve 0 of said-cock is perforated, as shown at 0 the effect whereof isthat water passing into inlet-orifice c flows through perforation c and5 then rises, in conduit at until it reaches groove a,-fills the same,and then overflows edge or wall a, and drops into the bowl A, from whichit passes to the trap. The cap B dipping into the running water ingroove a, a

seal is thereby formed for bowl A, the waterof which is constantly beingchanged. Where water is used for the sealing-fluid in groove to theflushing-pipe E must be continued up until the bend c of the samereaches the desired height to be given to the sealing-water in groove a.Otherwise the water would not rise in conduit a and groove to to suchheight; but if said conduit be dispensed with, and mercury or similarmaterial be employed to effect the seal in groove a, then theflushing-pipe will be arranged as shown at E, inwh-iich case the runningwater will. pass from cool: 0 to flushing-pipe E, and" thence to bowl Aand trap. Such arrangement provides a runningwater seal for the traponly.

Fig 2 shows the ordinary form of watercloset cock, perforated in orderto obtain the running or constantly changing water-seal, and Fig. tshows such cock attached to bowl A. The latter is represented asprovided with a mercuryrseal atf, its capB havingits flange b lined bothexternally and internally with porcelain or other similar materialtoprevent dampness from oxidizing theiron ofsaid flange. The cock U isprovided with a drip cup, h, which is connected'to bowl A by small traph, whereby the drip from said cock is conducted into said bowl withoutpermit-ting gas or odor from the latter passing into the apartmentwherein said closet is located. I

In Fig.3 I have shown my improved seal applied to that class ofwater-closets wherein the seat I is attached directly tobowl A, and thehinged lid 6 is provided with the sealing cap B, screwed or otherwisesuitably secured thereto. h is the drip-pan for the cock, and'which alsoforms a trap for opening '6, leading from said pan to the bowl A. Inthis case the run- ,ning seal for groove a and bowl A is provided for bymeans of a branch pipe, k, leading from water-supply pipe L. Said branchis valved, as shown at k, the regulation of whichadjusts the amount ofwater continuously admitted to groove (1 and thence to bowl A.

In Fig. 5 I have shown the running seal applied to a water-closet bowlprovided with a pan, M, operated by means of a rack and pinion, as shownor, if desired, said pan may be manipulated by means of the bevel-wheelgearing shown in Fig. 6, in which case the pulland push rod m is rotatedinstead of being moved upwardly and then downwardly, as is ordinarilythe case. The water from the supplypipe L,-when the construction shownin- Fig. 5 is employed, first enters the push rod chamber or tube N. Thewater rises therein until it finds its exit therefrom through the trapa, connecting the tube N and bowl A. After passing through trap-pipe nit enters bowl A and pan M, forming a seal therefor, as shown in saidFig.5. When such water has accumulated in the pan to such an extent thatit overflows theretrom it falls into and passes out through the trap Oto the soil pipe. In the construction shown in Fig. 1 the water, when itoverflows the edge a of groove a, falls into the trap O-below the bowl.Such water, constantly flowing into said groove a, seals the flangeofcap B and prevents the escape of sewer-gas from the bowl. The sameet't'ecttakes place when the pan M is used, only in this case the loweredge or rim of the boul A is sealed by the water contained intsaid pan,as plainly shown in Fig.5. Hence the cap B and the pan M, when used inconjunction with the bowl A and running water supply, serve to effectalike result'viz., the formation of a seal for said bowl for preventing.the passage of sewer-gas therethrough. The pipe M in Fig. 5 is designedto be provided with a cock, C, having perforated valve, as abovedescribed, for regulating the supply of water for chamber N and bowl A.

I have shown the running-water seal applied to water-closets, for whichI have already applied for Letters Patent of the United States;

water'closet how], so that the running water seal may be placed at thetop of the bowl, or, if desired, maybe located at the bottom of saidbowl.

What I claim as my invention is-- 1. In combination with a water-closetbowl, a cap or cover, a water-supply pipe, and a valve therefor,constructed and arranged substantially as shown and described, wherebyastream or a flow of water is caused to continuously pass through thewater-supply pipe to form a running-water seal between said bowl and thecap or cover, substantially as set forth.

2. A water-closet bowl provided with a sealing groove and a cap or coverdesigned and adapted to enter said groove, in combination with awater-supply pipe furnished with a cock, constructed and arrangedsubstantially as shown and described, whereby a stream of water willcontinuously pass through said pipe and into and out of saidsealing-groove, as and for the purpose set forth.

In testimony that Iclaim the foregoing I have: hereunto set my hand this30th day of August, 1881..
